There are a few considerations to make.
Make sure you are having lights on only during times that you are going to be available ideally.
Set schedule around power savings incentives, some states/companies have summertime discounts if you use your power at night vs day when it's hot during the summer. For me my kw/h cost goes from 0.15 to 0.18 during "peak times" so I run my lights at night. This will really matter if you are pulling a lot of watts. 1000w = 1kw
